hi,
my wife is 34 wks pregnant, and is having like waves of icy-hot feelings inside her tummy. she says its like a combination of a hot flash and a cold chill at one time- but its inside the stomach. we've been through the normal aches and pains, but this one seems kinda different.
Any thoughts? Anything to worry about?

OMG, someone else is getting this too?
I'm 37 weeks, but for the last few weeks I have been getting a similar sensation. I liken it to the feeling of cold or hot water being poured on the top of my belly, right below my left b___st. The first few times it happened I actually put my hands in my shirt to see if I was leaking, but there was no fluid. Just that really strange sensation! My midwife said there is a very wide range of normal pregnancy effects, and this is probably just one of them (although she's never heard of it before)

I'm glad I'm not alone! I called my doctor about it and she asked me to come in. After she confirmed that everything was great, she also informed me that my hot belly flashes were likely a side-affect of the contractions I have been having! Apparently, I am having them pretty regularly - even when I don't feel them like BH contractions. She said it is nothing to worry about since my cervix is not ready for the big event yet - but it did make me awfully nervous!!!
